A novel inorganic hydride material, hydrogen bismuth chromium oxide (HBi₃(CrO₄)O₃), with 2D nano sheets and 1D nanorods were prepared for the first time using a simple, green, hazard free hydrothermal method. The X-ray diffraction (XRD) results confirms that the as-formed sample (HBi₃(CrO₄)O₃) has monoclinic crystal system with a space group of P21/a. The field emission scanning electron microscope (FESEM) analysis clearly reveal that the new material contains large quantity of 2D nanosheets of thickness <10 nm and spread over >1000 nm and with small amounts of micro-rods of width in the range of 1 to 5 μm and lengths in the range of 40 to 100 μm. The EDS analysis confirms the presence of ‘Bi’, ‘Cr’, and ‘O’ and it further evidences the purity of the sample. The fourier transform infra-red (FT-IR) spectra evidences that the sample has Bi-H, Bi-O and Cr-O bonds as expected for HBi₃(CrO₄)O₃. This material has a potential to find its place in hydrogen storage material, photo/electro catalysis, fuel cells, optoelectronics and rechargeable batteries, therefore it needs materials researcher attention immediately.

首次使用简单、绿色、无害的水热法制备了一种新型无机氢化物材料，即氢铋铬氧化物 (HBi ₃ (CrO ₄ )O ₃ )，具有二维纳米片和一维纳米棒。X 射线衍射 (XRD) 结果证实，所形成的样品 (HBi ₃ (CrO ₄ )O ₃ ) 具有空间群为 P21/a 的单斜晶系。场发射扫描电子显微镜 (FESEM) 分析清楚地表明，新材料包含大量厚度 <10 nm 且分布超过 1000 nm 的二维纳米片，以及少量宽度在 1 到 5 之间的微棒μ m 和 40 至 100 范围内的长度微米。EDS 分析证实了“Bi”、“Cr”和“O”的存在，并进一步证明了样品的纯度。傅立叶变换红外 (FT-IR) 光谱证明样品具有 Bi-H、Bi-O 和 Cr-O 键，正如 HBi ₃ (CrO ₄ )O ₃所预期的那样。这种材料有可能在储氢材料、光/电催化、燃料电池、光电和可充电电池中找到一席之地，因此需要材料研究人员立即关注。
